YOPP/YOPP+ is a fully formulated pellet composed of bio-based and biodegradable poly-3-hydroxybutyrate (PHB) polymer, which is produced through microbial fermentation utilizing either plant-derived sugars (YOPP), waste methane (YOPP+), or a blend of both as the primary ingredient. The ST grade is specifically engineered for injection molding of rigid products and exhibits mechanical properties comparable to those of polypropylene.
